m68k: Increase initial mapping to 8 or 16 MiB if possible
If the size of the first memory chunk is at least 8 or 16 MiB increase the
initial mapping to 8 resp. 16 MiB instead of 4 MiB.
This makes it possible to
1. Map more memory in the first node without running out of space for the
page tables,
2. Boot kernels that don't fit in 4 MiB (e.g. multi_defconfig).

- Add support for 8 MiB,
- Store initial mapping size in head.S for later reuse,
- Add comment about large kernels.
